Necessary Pre-Press Equipment for Screen Printing
You can either purchase a manufactured drying rack or create one of your own. Either way, you need a spot for your screens to lay horizontally after you coat your emulsion and its in the drying stage.
When it’s time for your screens to be exposed, always after applying emulsion, you’ll need a piece of equipment called an exposure unit. All of this needs to happen before your screen hits the press.
You’ll need a washout station and water source to rinse out your screen after exposure as well as reclaiming your screen after a press run.
Screen Printing PrePress Preparation
A majority of screen printers focus on perfecting their own screen printing operations. This includes having the right off-contact, squeegee angle and pressure as well as ensuring the right exposure time. When it comes to setting up an accurate press run, it all starts with pre-press operations.
You need to find the best products that work well for your shop and your budget. On another note, a darkroom is highly important for prepress.
Prepping Your Screens
Before starting the exposure of your screens, you need to perform two different checks. The first is to make sure you have a humidity gauge somewhere in your dark room. Having a humid dark room is imperfect conditions for your emulsions. By having the right temperature and humidity levels, you’ll have your emulsion stick better to your screens and dry thoroughly. You also need to make sure your screens are taut and have the correct amount of tension, otherwise they’ll cause blurry prints and poor registration.
After ensuring the accuracy of your dark room and screens, you need to make sure your screens are absent of dirt and dust. Use degreaser for cleaning as well as adhering your emulsions. First focus on adding emulsion the side of the screen that will come in contact with your substrate, working from top to bottom with a scoop coater. You must also correctly dry your screens in a horizontal position, and you can place your rack in a washout station.
The next phase includes exposing your screens, which can be done with an exposure unit.
Prepping Your Machines
Another good step in the Prepress process is to always check your machines. You might be using your machine all day long, but you should make adjustments between each screen printing run.
Once you’ve finished all of these steps including proper exposure of your screens and prepping each machine, you can start your screen printing run! Remember, the best way to begin any project is to have the correct setup. Don’t skip out on using all of the different kinds of prepress machines that will help you transition easily to using your screen printing press.
Why Do I Need An Exposure Unit?
Exposing your screens is a crucial step in the screen printing process. You could go outside and try and use natural sunlight for exposure, but you can’t rely on the sunlight. You don’t have control over the temperature or how long you will need to leave the screen. Instead of making it a hassle, invest in an exposure unit to avoid underexpose screens. These helpful, affordable units help you create high quality artwork and produce high quality screens.
Is it Important to Prep Ink?
Preparation for your ink will depend on what kind of ink you use in your shop. One of the best ways to prep your ink is to use a color matching system and a pantone guide. By using a color matching system, you’ll be able to mix your own colors to achieve your desired match. When you try to combine inks, you will need to mix them. You can do this manually with screen printing tools or you can utilize a ink mixer in your prepress process.
Why Do I Need to Degrease My Mesh?
Some screen printers don’t invest in good quality degreasing products. By finding the right degreasers, you’ll spend less time worrying about the washout process. By using a degreaser, your emulsion will adhere better to the mesh during the exposure process. You also can’t forget to degrease both sides of your frame (seeing that they both hold contaminants). You also need to correct dry your screens either in a washout booth or with a conveyor or flash dryer.
